How to set up SPDIF passthru to external decoder?
SPDIF paththru depends on the decoder doing the job. So it's really simple to adjust. Of course, there should be a proper audio driver/directx and h/w setup in your system. SPDIF settings in the preferences of KMP only have an effect on the case of internal audio decoder. In case of external audio decoders, you should set it up properly in the property window of the audio decoder to use.
The following screenshots are the typical settings of some audio decoders.
The default AC3/DTS decoder of KMP is AC3filter. You can refer to the documentation of the AC3fitler.
